My invention relates to improvements collapsible perches for poultry nests.

V The object of improved means for preventing froinentering the nests at night. I I More particularly stated "it is theobject of this invention to provide means whereby an ttendant may by a singlemovement of the hand or arm adjust a seri of perches to a position'ot non-use along a nesting cabinet havlng one or more this invention 13 to provide chickens by saidperches when so "adjusted will be terior structure of the cabinet tormsno part,

1 T he cabinet 1 may be of any ordinary type adapted to be connected with a supporting wall or held in a raised position by any suitable means. It is preferably provided With a sloping roof 2 to prevent "fowls irom roosting thereon. The interiorzis suitably subdivided'nto nests each having an opening 3 through which the {owls 'inay enter. It is not deemed necessary to illustrate the partitions which subdivide thenests, since the in- 7 oi this invention.

Chains 14inormally support the perch 11 and-the arms 12 in ahorizontal position, said chains being connected with the cabinet i 'The upper perch 11 V L Lower perch having a set ot'perch bars 5 l f6 4 is. supported troml the cabinet walls arms 7 pivoted to the" wall bracketsS. ine pivotal axis 9 is located at a substantial distance in front or the cabineti, whereby when; the arms 7 are swung upwardly, their will be carried across avertical. planethrough the pivot axis, the upperperch bar-5 resting against theiront wall of the cabinet as is clearly shown in Fig. I 's similarly supported by pivoted arms 12 frointhe wall'brackets at 15 above the bracl ets,13.-. V v p I The arms 12'are connected to the arms- 7 of the lower perches by links 17, whereby,

when the arms 12 are in a horizontal p0sif tion, the arms ,7 will be held by the links 17 ialso in a horizontalposition. But'by lifting pressure exerted upon either pf the perches 501x601 ugon either o' f the arms 7, these perches may be ira sed to" the pos tion in g l in an aarrsreee which they are showninFi'g. 2 and while;

they are being so raised their motion will be transmitted tothe arms} 12 and perch 11 through thelinlrsi- 1? It willalso be observes that the-arrangement 18 such that the lower perches will support the upper ones when; intheraised position, even though the upper perch or perches may not becarried acrossa vertical plane through their respec-' tive ares. This isnot-only.dueto'tlle. fact that the lower perch or, set of perches, inthe construction illustrated, is of. greater Weight and the swinging arms?- of greater length than the upper perch, but it s also due to the -I 1Ct that iniraisingtl ieperches-the lower end aot the links 17 swing past a vertical plane through the pivotal ax is 9 and, there? fore, the weight'ot'the upper perch, when in an outwardly inclined position,vis exerted to press the lower perches supporting arm; more firmly against the cabinetat' their upper ends. This result is facilitated by' making the brackets 8 longer than the brackets 13 or at least by locating the pivotal; connec tions 9 at agreater distance from the cabinet than the pivot pins 19. connectingthe.

illustrated a nesting cabinet having but two superposed tiers of nests and two perches at differing levels associated: with the respecia'rms 12 withthe brackets 13. ",VVhile lhave tive tiersotnests, 'it'will be understood that the; number ot perches connected 1-7. correspond ineach casewiththenumber, of

It will be observed that the link con motions, with the upper and lower sets ot' barsrespectively, are at differing distances from the cabinet, but at the same distances from the pivots about which the respective b ars swing.

Therefore, the perches can be raised to the folded positlon wlthout requiring any sliding movement of the links on their pivotal connections. 7

I cla11n:

1. In a device of the character described,

the combination with vertically spaced supports, of perch supporting arms each p1vcted'to one of said supports, and a linkconnecting the arms, the arc of movement of one of the arms about its pivot being so related to the arc of movement of the other of the arms about its pivot whereby to permit one of the arms to move across the plane of the link beforethe other of said armsmoves to said plane.

'2. The combination with a nesting'cabinet'having superposed nests, and associated perches adapted to facilitate access to the nests, each of said perches having arms pivotally supported by the cabinet, links con "necting the perches, and means for-holding the perch supportingarms normally in a hor zontal position, said'arms and perches h'fbein' 'ada Jted for an n wardl' SWl11 111 b i b b l "movement to a position of non-use with the supporting arms of one of the perches inclined upwardl 'andinwardly against the wallof-t-h'e cab inet and with the supporting arms of the other of the perches inclined and outwardly from the wall of upwardly the-cabinet. v V 3. The combination with a nesting cabinet having apertures at different levels affordi'ng access to the nests,of sets of perchsupporting brackets associated with the apertured portions of the cabinet, perch sup porting arms pivoted to'said brackets in front of said cabinet, perches mounted on said supporting arms and adapted to swing upwardly to positions across the associated apertures, links connecting the upper and lower perch-supporting arms, and supporting means for limiting the downwardly swinging movement of said arms, said pivotal connections of the suppm'ting' arms being so located with reference to the cabinet as'to allow one of said arms to swing across the vencal plane of their pivotal aXes toan inclined position against the wall of the cabinet.

4:. The combination with a nesting cabi' net having'apertures at different levels affording access to the nests, of sets of perchsupporting brackets associated with the apertured' portions'ot the cabinet, perch-supporting arms pivoted to said brackets in tront ot the cabinet, perches-mounted on said supporting-armsand adapted to swing upwardly to positions across the associated. apertures, links connecting the upper and lower })6l'Cl1SUPPOYtlDg arms, and chains ing' the arms of the respective sets at (lit fering distances from the cabinet, and links connecting the arms of said sets at the same distance from their respective pivotal c connections. 6. Ina device of the character described,

the combination with supports, of perchcarrying arms pivoted to said supports'at differing levelsfa perch supported from the arms at each level, and a link connecting.

the arms supported at Clili BiQHhlH QlS, the fulcrum points of one of the arms to which said link is connected being so disposed with reference to i'aid link that said arm will move pivotally across the plane of said link toward a position for contact with said support before the other arm to which said link isrconnected' moves pivotally to its extreme position.
